CLOSURE FOR BUCK ETS OR PAILS.

SPECIFICATION forming part of Letters Patent No. 657,045, dated August28,1900. Application filed May 25, 1899. Serial No. 718,181. (No model.)

To all whom it may concern.-

Beit known that we, DAVID E.TRAINER and PAUL B. M. TRAINER, citizens ofthe United States, and residents of Philadelphia, Pennsylvania, haveinvented certain Improvements in Closures for Buckets and Pails, ofwhich the following is a specification.

Our invention has been devised especially for use in connection withpails or buckets for containingchern ical fire-extinguishing liquids,the object of our invention being to provide for securing the lid orcover to the pail in such a manner that while it is hermetically sealedit can be instantly removed in case of fire.

Our invention is also applicable to buckets or pails for other purposes.

In the accompanying drawings, Figure 1 is a sectional View of a chemicalfire-pail with lid or cover secured thereto in accordance with ourinvention. Fig. 2 is a plan View of the pail and its lid or cover beforethe sealing agent has been applied to the latter, and Fig. 3 is asectional view illustrating aslight modilication of part of theinvention.

1 represents the pail, which has some distance below the rim an internalrib or shoulder 2, upon which is seated the outwardly flaring or beveledflange 3 of the lid or cover t, the latter having a central handle 5,whereby it may be readily lifted. The flaring side of the pail and theflaring flange 3 of the cover 4: form a ti-shaped chamber for thereception of the sealing agent 6, which provides a hermetically-sealedjoint between the lid and. the pail, thereby preventing not only theaccidental removal of the lid and the access of unauthorized ormischievous persons to the contents of the pail, but also preventing theevaporation of said contents when the pail stands unused for a longtime. In case of fire, however, the pail should be ready for instantuse. Hence some means must be provided for instantly releasing the lidor cover 4. For this purpose we employ a sealing agent, such asparaffin-wax or other material or compound which can be readily cut, andwe lay a wire 7 at the bottom or apex of the V-shaped groove beforefilling the same with the sealing agent, one end of this wire passingthrough the seal and extending out over the lid, as shown at 8, and thisprojecting portion of the wire being bent at the end, so as to form aring 9 or other handhold, whereby the wire may be readily grasped. Incase of fire, therefore, a quick pull upon this projecting portion ofthe wire will cause the embed ded portion 7 of the same to cut throughthe seal, and thus release and permit of the immediate removal of thelid or cover 4, the fact that the wire occupies the very bottom or apexof the V-shaped sealing-groove insuring the complete severance of thesealing agent, as there can be no portion of the latter beneath the wireto hold the lid in place after the wire is withdrawn, because the lid orcover has only an edge bearing upon the rib 2, and hence does notpresent an extended sealingsurface,which would resultin such anattachment of lid and pail as would prevent the ready pulling of the lidfrom the pail after the Withdrawal of the wire.

If desired, the flange 3 upon the lid 4 may be straight instead offlaring, such modification being illustrated in Fig. 3.

In the lid or cover at is an opening surrounded by a screw-threadedflange 10, to which is adapted a screw-cap 11, this opening providingfor the introduction of the contents of the pail after the lid at hasbeen sealed in its place, so that at the place of manufacture the pailsmay simply have the chemical substance or compound placed in them andmay be filled up with Water through the opening in the cover after theyreach their destination, said opening being subsequently closed by theapplication of the screw-cap 11. Hence the trouble and expense oftransportation of the body of liquid with the pail from the place ofmanufacture to the point of use are overcome We are aware thatit is acommon practice to connect two portions of a metallic vessel by asealing-band which can be torn away, so as to release said portions fromconnection with each other, and such construction therefore we do notclaim; but

We claim as our invention and desire to secure by Letters Patent-- Thecombination of a pail or bucket, havin g an inwardly-projecting ribbelow the top, with lid or cover having a flange with its thin edge onlybearing upon said rib and forming with the portion of the bucket abovesaid rib a tapering or V-shaped groove for the reception of a sealingagent, so that an extended sealing-surface between the lid or cover and.the bucket is prevented, and a releasing-wire located at the base orapex of said groove and having a portion projecting through the seal sothat it can be grasped in order to pull out the wire, whereby the lid orcover may be readily pulled from the pail upon the withdrawal of thewire, substantially as specified.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
